What happens when you call -init multiple times on one object, are there some hidden side effects?
Can you assume that no additional memory is allocated?
Would anything go against such an idea?
Calling
-initmultiple times is undefined, unsupported, and will lead to bugs, crashes, and other unexpected behavior.Many classes —
NSString,NSArray, andNSDictionary, for example — don’t actually allocate anything when the+allocmethod is called. It isn’t until one of the various-init*methods are called that the object has enough context to figure out the most efficient means of doing whatever you ask.
